Find Hierarchical Data Format (HDF5), a library for reading and writing self describing array data.
This module invokes the HDF5 wrapper compiler that should be installed alongside HDF5. Depending upon the HDF5 Configuration, the wrapper compiler is called either h5cc or h5pcc. If this succeeds, the module will then call the compiler with the show argument to see what flags are used when compiling an HDF5 client application.
The module will optionally accept the COMPONENTS argument. If no COMPONENTS are specified, then the find module will default to finding only the HDF5 C library. If one or more COMPONENTS are specified, the module will attempt to find the language bindings for the specified components. The valid components are C, CXX, Fortran, HL. HL refers to the “high-level” HDF5 functions for C and Fortran. If the COMPONENTS argument is not given, the module will attempt to find only the C bindings. For example, to use Fortran HDF5 and HDF5-HL functions, do: find_package(HDF5 COMPONENTS Fortran HL).
This module will read the variable HDF5_USE_STATIC_LIBRARIES to determine whether or not to prefer a static link to a dynamic link for HDF5 and all of it’s dependencies. To use this feature, make sure that the HDF5_USE_STATIC_LIBRARIES variable is set before the call to find_package.
Both the serial and parallel HDF5 wrappers are considered and the first directory to contain either one will be used. In the event that both appear in the same directory the serial version is preferentially selected. This behavior can be reversed by setting the variable HDF5_PREFER_PARALLEL to TRUE.
In addition to finding the includes and libraries required to compile an HDF5 client application, this module also makes an effort to find tools that come with the HDF5 distribution that may be useful for regression testing.
This module will set the following variables in your project:
Available components are: C CXX Fortran and HL. For each enabled language binding, a corresponding HDF5_${LANG}_LIBRARIES variable, and potentially HDF5_${LANG}_DEFINITIONS, will be defined. If the HL component is enabled, then an HDF5_${LANG}_HL_LIBRARIES will also be defined. With all components enabled, the following variables will be defined:
The following variables can be set to guide the search for HDF5 libraries and includes:
